gpu: nvgpu: move resetup_ramfc to common channel

Browse Source 
On gp10b, ramfc contains information related to syncpoint
protection, which restricts the syncpoint increment operation
to a safe set of syncpoints. This information must be
updated when a syncpoint is assigned to a channel.

Added the following ramfc HALs
- ramfc.get_syncpt
- ramfc.set_syncpt

And replaced
- fifo.resetup_ramfc

With
- channel.set_syncpt

Use new ramfc HALs, move resetup_ramfc implementation
from fifo to common channel code:
- nvgpu_channel_set_syncpt

NVGPU-1750
